pine propogation

I understand that pines tend to be difficult to propagate by cuttings.
I recently found what I believe is a witche's broom on a red or
austrian pine and would like advice on how to try to propagate
it--preferably by cuttings as I have no experience or stock for
grafting. I have a hot frame and greenhouse/propagation chamber.
Thank you.
